MINISTRATRIX, OF TULSA, OKLAHOMA, ASSIGNOR TO WESTERN SUPPLY COMPANY, OFTULSA, OKLAHOMA, A CORPORATION OF OKLAHOMA AUXILIARY LINER Applicationfiled March 3,

This invention relates to new and useful improvements in liners for wireline clamps.

The invention has particularly to do with a liner for use with a wireline clamp of the type shown in the Letters Patent No. 1,728,173, issuedSeptember 17 1929, but may be applied to any clamp suitable for thepurpose.

One object of the invention is to provide an auxiliary liner arranged tobe fitted into the regular liner of the clamp to take a smaller size ofline when necessary.

Another object of the invention is to provide an auxiliary liner in theform of an attachment which may be readily applied and as easily removedwithout disconnecting, disassembling, or in any way disturbing the partsof the clamp.

A construction designed to carry out the invention will be hereinafterdescribed, to-A gether with other features of the invention.

The invention will be more readily understood from a reading of thefollowing speciflcation and by reference to the accompanying drawings inwhich an example of the invention is shown, and wherein:

Figure 1 is a plan view of a wire line clamp equipped with an auxiliaryliner constructed in accordance with the invention,

Figure 2 is a perspective view of the auxiliary liner,

Figure 3 is a partial vertical sectional view of the clamp and liner,and

Figure 4 is an enlarged transverse sectional view showing the clampliner and the auxiliary liner gripping an undersized line.

ln the drawings the numeral 10 designates a yoke shaied body includingan outwardly directed arm 11. At the center of the body is formed aconcaved vertical liner boss 12. A jaw or arm 13 is suitably hinged tothe body and is actuated by a lever 14. The jaw also has a verticalconcaved liner boss 15 opposite the boss 12.

The boss 12 has a liner 16 fastened therein by set screws 17 while Vtheboss 15 has a complementary liner 18 fastened therein by set screws 19.Each liner is formed by a cylindrical bar provided with diametricallyopposite longitudinal concaved grooves 21.

1930. serial no. 432,935.

Vhen one groove becomes worn the liner may be reversed and the othergroove used.

Upon swinging the lever 14 toward the arm 11 the liner 1S will receivethe cable or line in its groove 21 and ordinarily seats that cable inthe groove 21 of the liner 16. Often it is desired to clamp a smallercable or line, such as a sand line on a derrick and the grooves 21 wouldnot conform to the small diameter of the sand line and, therefore7 wouldnot clamp the same.

In such instances an auxiliary liner 22 is employed. This liner has ahook 23 at its upper end provided with a down-turned bill or stub 24. Inthe face of the liner is provided a vertical concaved groove 25 formedon such a curvature as to coact with the groove 21 of the liner 18 togrip a smaller line. The boss 12 is provided with a socket 26 in its topso that the liner 22 may be fitted in the groove 21 of the liner 16 andthe bill 24 engaged in the socket 26, whereby the auxiliary liner isheld in place. It will be seen that the liner will properly grip thecable and may be easily and quickly applied or removed.

The lever 14 is connected with an operating lever 27 by a gate 28,whereby the clamp is operated. It is not considered necessary to go intothe details of the operation of the clamp. It is pointed out that theauxiliary liner 22 may be applied to any concaved liner and the hook orsome other fastening means provided for temporarily securing theauxiliary liner in place. It is important that the liner be fittedwithout disturbing the other parts of the clamp, making adjustments oralterations.

Various changes in the size and shape of the dierent parts, as well asmodifications and alterations, may be made within the scope of theappended claims.

Vhat is claimed, is:

1. The combination with co-acting line gripping liners, of an auxiliaryliner removably attached to one of said liners and having a groove forreceiving a line of less diameter than said liners.

2. The combination with co-acting line gripping liners having opposedvertical line grooves, of an auxiliary liner removably litting in thegroove of one of the liners and having a vertical groove for receiving aline of less diameter than the grooves of said liners and cio-actingwith the groove of the other liner.

3. The combination Wit-l1 a Wire line clamp having co-acting linegripping liners provided with vertical line grooves, of an auxiliaryliner engaging in the groove of one of the liners and having a hook, atits upper end engaging in the clamp for removably securing it in place,said auxiliar57 liner having a vertical groove for receiving a line ofsmaller diameter than the clamp liners.
